Constraints, at their most basic, are controllers that control how one item relates to another. Constraints can serve many purposes and, when you use them in combination with other constraints, you can create very complex controllers and motions. Modo's constraints are weighted. A weight value determines the influence a constraint has over the item it's controlling.
